The floor of the passage is green, and it looks like rubber when stepped on, but it is a little different. The bottom half of the walls are green, the top half is white, and the passages are a little stuffy, unventilated, and very damp. Yuan Dou swept by quickly, and from time to time he could see blocks of garbage, which seemed to be rarely cleaned up. Probably, someone will check here, but certainly not too often.

The straight passage turned a corner, and in front of it was a double-open fire door. There was glass on the door, and Yuan Dou looked in against the door, and several huge machines blocked the view, so he couldn't see anything else at all. I don't know which machine started suddenly, and the noise was amplified many times at once. Yuan Dou was about to push the door and go in when he suddenly felt something vibrating on his body. I touched my purse, it was his communicator, and it was a call from Xunlan.

"Hey, any news?" Yuan Dou asked.

"You're so noisy there, I can't hear you clearly."

Yuan Dou took the communicator away and turned on the anti-jamming mode. "Are you okay now?" Yuan Dou looked at the inside of the glass again and again, while contacting Xunlan. He told Xunlan everything he found, "How is it, do you have any ideas?" ”

"Yours makes sense, but I'm definitely not going to have a good chance of them being in the mall again."

"Why so?" Yuan Dou had already pushed the door and walked in. After a rough look, there was not half a figure here, except for a few machines that were making noise like crazy. Just as Yuan Dou was complaining, the machine in operation suddenly stopped. All of a sudden, it was so quiet that even the sound of water droplets was clear.

"It's likely that they're down there, only there, where the signal is jammed and can't be reached, and where they can escape from the surveillance range."

"Are you sure?" Yuan Dou asked subconsciously.

"That's my guess."

Mototo walked to a corner, where there was an open sewer, and there were marks on the edge of the dirt that had been crushed and deformed for a long time. "I think you're right, they should have left the sewers."

"What did you find?"

"A sewer that hasn't been open for a long time."

"Heart, I may not be able to contact you there."

"Well, so be it!"

After Yuan Dou hung up the phone, he looked inside the sewer, and there was nothing in the dark. Yuan Dou jumped directly without hesitation, and after landing on the ground, he found that there was not too bad smell here. There is no difference between this and Hwaseong sewers, they are the same structure, but it may be that there is very little domestic wastewater, and the smell of water coming out is not too great. Yuan Dou couldn't imagine why Lian Yan and the others were here, he remembered that Lian Yan hated such a dirty environment and rats. Mototo took out the box of foundation he had just seen at the place where he was selling makeup. At that time, he noticed that this thing was strangely thrown in the corner. There's nothing special about this thing though, just a regular foundation, exactly like what's on the counter. However, Yuan Dou felt that this thing should have something to do with why Lian Yan and the others came here. Yuan Dou held the foundation box and closed his eyes, imagining what Lian Yan would have been holding it at that time. Then, he opened his eyes and rushed forward.

The sewer mouth where Yuandou came down is the head, and there is only one road ahead. Not long after walking forward, Yuan Dou encountered the first crossroads. Yuan Dou couldn't tell which direction it was, so he could only stop and search for clues. "Yin, scan the surrounding environment and look for clues related to Lian Yan and Ye Xi." Yuan Dou stretched out his hand and stood on the left side of the intersection. Silver emitted a blue light and spun in a circle, and it didn't take long to get an answer. Yuan Dou was a little disappointed, "No, then there are no other special things?" Yuan Dou asked again. Along the way, Yuan Dou didn't see any traces of fighting, with their strength, even if the other party was a professional, they could still leave traces, and the only reason Yuan Dou could think of was that they were restricted, and the specific situation was unimaginable.

"It is advisable to broaden the scope of your search." The voice of the silver anthropomorphic sounded, and Yuan Dou immediately accepted the suggestion. This time it took a lot longer, and it took about three minutes before Silver finished searching.

"After many screenings, a special odor remained in the air, and the similarity to the target reached 90 percent." Silver glowed red, and could only illuminate a long distance. But when the red light came up, particles of the same color floated in the air in the distance, extending all the way to ten meters away.

"Is this the clue you found, do I just have to follow the instructions?" The effect of silver exceeded his expectations, and Yuan Dou was a little excited, and his voice was raised a lot.

"Tracer rays can illuminate particles at the molecular level, and its resolving power is 10,000 times higher than that of humans." Silver.

Yuan Dou took care of this, he just needed to know to follow the red particles. Yuan Dou raised his left hand and ran with the red light. There were no stops at various intersections along the way. After a few minutes, he stopped, and there should have been a dead end in front of him, but there was a large hole in the wall. The particles that emitted red light extended all the way inside, and Yuan Dou only hesitated for a moment before walking in. The thickness of the walls reached five meters, and it was as if Yuan Dou had walked into a type tunnel. And after walking over, the scene in front of him shocked him.

He had already left the sewer range, and at this time the place was more like a cave, and one thought that the cave built, more accurately, should be an air-raid shelter. It was a much larger space than a normal room, and the top light was on, emitting a dim yellow glow. It was an old-fashioned electric light that was explosion-proof and is now largely invisible. The space was disorganized, as if there had been a lot of stuff piled up, but now someone didn't know who had moved it, leaving only a pile of debris.

The bomb shelter is generally large, but the scale of this bomb shelter is beyond imagination. Yuan Dou passed by many rooms like the one just now, and even saw a rusty six-wheeled truck in the room. And with such a truck, Yuan Dou feels that he can run three side by side in the passage. This is not an ordinary bomb shelter, this is supposed to be a bomb shelter as a military facility. It is likely that before the new era, it existed as a military powerhouse, but the war has regressed the earth's civilization for many years, and I don't know how many places have been abandoned like this, and no one knows what is still hidden in it, and it is even possible to hide the atomic bomb, the hydrogen bomb, which is known as the strongest weapon on the earth.

Walking through an equally large space again, I faintly heard something. Yuan Dou cautiously lowered his pace, while also using the concealment technique. The sound came from outside the passage that was about twenty meters long, and Yuan Dou slowly approached until he could see the situation outside the passage, and he stopped.
